A water-reducible composition comprisesn (A) from 20 to 50 wt% of a water-insoluble nigrosine, (B) from 25 to 40 wt% of a solvent having a flashpoint of at least 141°F (61°) and a boiling point of at least 280°F (138°C), and (C) from 20 to 40 wt% of a non-ionic surfactant, the weight percentages being based on total weight of (A), (B), and (C). n The composition is prepared by dissolving the nigrosine (A) in a C 1 -C 3 alkanol to form an alcohol solution, mixing the alcohol solution with the solvent (B) and non-ionic surfactant (C), and subsequently stripping the C 1 -C 3 alkanol. |
